i had a SCS put in about a year after being diagnosed with RSD... the trial worked great for me, however the perminant one caused my RSD to spread and then failed to give me the pain relief afterward. Needless to say I had it removed about a year and a half after having it implanted.

If you scroll through a couple pages of topics on here there are some surveys I posted from a bunch of different people with RSD that i took for information for a paper I was writing (That as well is posted on here some where). But one of the questions on there asks about the treatments/medications they've tried. That may help you out some.
